Abstract:

It was studied to the precise fertilization mode for vegetables domain in Wuhan Dongxihu district by application of modern information technology. Through the positioning sampling, testing soil effective nutrient, establishing a spatial database based on land parcel, soil nutrients distribution map at village domain were plotted by GIS software. Combined with nutrient plentiful-deficiency index table made before, it can be applied to recommend for vegetables fertilizer amount as precise fertilization mode orienting to each land parcel of village domain. This mode is suitable for southern agriculture area, especially suburb planting vegetables. Also I was discussed to modern agricultural development, to explore the long-term mechanism of formula fertilization by soil spatial database in the article.
